UNIVERSAL HOLDING-BRACKET' FOR POWER UNITS.

Specification of Letters Patent.

Patented June 17, 1919.

Application filed April 20, 1918. Serial No. 229,872.

T 0 all whom it may concern:

Be it known that l, MILTON M. KOHN, a citizen of the United States,residing in borough of Manhattan, in the county of New York and State ofNew York, have invented certain new and useful Improvements in UniversalHolding-Brackets for Power Units, of which the following is aspecification.

My present invention relates to a universal holding bracket for holdingin operative position certain desired forms of power units such aselectric motors and the like.

Another object of the present invention is to provide insuch universalbracket a suitable frictionless bearing whereby the power unit graspedtherein may be provided with an additional bearing, forming,substantially, a foot-step bearing for such motors when the device isoperated in a vertical position.

Another object of the invention is to provide suoli adjustable motorholding means with a simple and efficient means of adjustment and lockfor all adjusted positions.

A further object of the invention `is to lprovide means on the'saiddevicewhereby any standard type of electricv motormay, withinv limits,be firmly'held between the grasping-means without it being necessary toprovide thehousings or other parts of such standard motors with aspecial coperating gripping means( On the other hand,

where 1t is deemed advisable, coperating gripping devices may beprovided upon the said motors. v Y j Another object of the invention isto provide means on-esaid gripping device of an extremely simple naturewhereby the gripping holder maybe readily and adjustably appliedto anyform of base or other supporting means so that such meansv will be uni-`versally adaptable. j

These 'and other features, capabilities, and advantages .of theinvention will appear from the subjoineddetail description of certainspecific embodiments thereof, in 'which- Figure 1 is an elevation partlyin section of one embodiment showing a motor anchored thereto. j

AFig. 2 is a small section substantially on the line 2.-?. of Fig. 1.

Fig. 3 is an elevation of another embodiment in which the fingers haveplain surfaces.

` above this, there is also provided a pivot bracket 15 upon which ismounted the gripping. arms 18, the said pivot bracket being providedwith its own locknut 14.

The bracket 15, when used for supporting i a motor or the like, isprovided with an annular recess or seat 16 at its free end, in thepresent instance the upper end, to receive the thrust-bearing A of usualconstruction which acts as a foot-step bearing for the supported device,in which coperates the shaft B of the motor M Fig. 1. Laterallyextending from the bracket 1 5 are provided the pivot lugs 17, forpivotally mounting thearms 18, the lugs being arranged inV pairs toreceive an arm 184 between them with a pivot pin 19 extending through apair of lugs 17 and an arm 18.

There are provided preferably three such arms 18, spaced'equ'idistant,each arm having a finger portion 19 `which coperates with the fingerportions of theother arms and with the device tobesupported, and eacharm having a fulcrum portion 20 to coperat'e with the fulcrum nut 13.The linger portions 19 in the embodiment illustrated in Fig. 1, may haveinner corrugated faces 21 to increase their graspingefiiciency and areshown engaging corrugated engaging plates C .formed on the motor M. Thelever arms 20 have inner fulcrum nut engaging faces 22 to engageithewedging face 23 of the fulcrum nut 13, preferably formed conical asillustrated. v

In operation, assuming that the bracket 15 has been set inplace on thethreaded portion 11, the locking nut 14: secured up thereagainst, thethrust-bearing A placed in the seat 16 of the bracket 15, whichadjustably supports the thrust-bearing A, the motor located with itsshaft B disposed in the bearing A, and the corrugated plates Cregistering with the linger portions 19,-the

sov

fulcrum nut 13 is then screwed-'up with its wedging face 23 engaging thefaces 22 of theV lever arms 20 until the required tension is produced,whereupon thel locking nut 12 is secured up against the fulcrum nut 13and the support is ready for use.

The embodiment illustrated in Fig. 3, is substantially the same as thatillustrated in Fig. 1, except that the finger portions 2i are providedwith plain faces 25 instead of the corrugated faces such as the faces 21of the finger -portions 19. Y

In the embodiment illustrated in Fig; 4, a-inger portion 26 is shownwhich has an adjustable cone point 27 mounted therein forengaging thedevice to be supported.

In the embodiment illustrated in Fig. 5, a linger portion 28 is shownprovided with a half round bore having aseat 29 for receiving the lowerend of a screw 30 which engages t'liethreads of athalf rouirdrece'ss 31formed in the device to be supported, and is anchored i-ntpositionbetween the device to be'supported and the finger portion 28v as shown.With thisarrangement, it i-s possible to adjust thel alineineiit of themotor axis relative to the support axis without disturbingtli'e tensionof the supporting` member;

Iii-the embodiment illustrated in Fig. 6,v

the ybracket 32 is not directly threaded to the threaded portion ofl thesupportingmember onstenr 10, as is the case with the bracket 15 oftheeinbodiment illustrated in Fig. 1. In this embodiment, the bracket 32is threaded onto an extension 33 formed onl a cup 84 provided with aseat 35 for receiving the thrust-bearing 36, the extension 33 beingthreaded to the threaded portion 37 of the supporting member; By thisarrairgei'nent,

itwill thus be possible to adjust the distance and bearing between thesupported power unit andthe supporting member without disturbingin anyway the adj ustment' alinement, axial orotherwise, of the supporting andsupported members. j

While I have nbtz shown any means of supplying: oi'l to the thrustvbearing A, it isobviousthat any well knownmea-ns of supplying suchlubrication' may be employed.

As previously noted, in order to render my gripping device of extremelysimple nature so that it may be readily 'and adjustably appliedto aceiling, desk, wall, Vor other desirable form of base, ornamental orother- Wise, the lower port-ion of the support is arranged in a stemform as at 10, Fig. 1, said stem being either cylindrical or square. Itis obvious that the various forms of bases above referred to need onlyhave a suitable bore to receive said stem'into which it may be rigidlyattached by any suitable fastening means ofthe customary type.

It is obvious that various changes and modifications may be made to thedetails of construction without departing from the spirit of myinvention, or exceeding the scope of the claims".-
